A (001) dominated conjugated polymer with high-performance of hydrogen evolution under solar light irradiationElectronic supplementary information (ESI) available. See DOI: 10.1039/c7cc06105f

A two-dimensional imide-based conjugated polymer with a preferred (001) orientation was constructed by solvent-induced assembly. A high performance of 1640 μmol h −1 g −1 for solar-driven photocatalytic hydrogen evolution and an excellent stability were achieved due to tunnelling charge transport between the neighbouring molecular sheets. A self-organized polyimide supermolecule with high performance in photocatalytic hydrogen production (1640 μmol h −1 g −1 ).
